This removes a lot of the plumbing for having the platform embed itself
through IPC which was required for B2G running the browser as both
shell and browser application.
Currently following Mozilla putting stuff in /dom for additional porting,
but it's actually the wrong location since it belongs in /netwerk with
the other code that deals with http headers.
This patch adds an enumerable, configurable, readonly attribute "webdriver" to
the Navigator object. The attribute is always false because we do not support
WebDriver or scripted automation.
The navigator.webdriver attribute is meant as an indication to web authors that
a document is visited by WebDriver. It is important to stress that it is not
meant as a way to detect that a website is being visited by a browser automation
tool or bot, but as a tool for web documents to take alternate code paths.
On the off-chance exposing navigator.webdriver turns out to be catastrophic,
we put it behind a new preference dom.webdriver.enabled that controls its
exposure.
The timings here are still slightly more lenient than the hard-coded
fallback timings in code (10/20 for content/chrome respectively) but
we definitely should not need very long time-outs by default on Chrome
scripts anymore.
Also exposes dom.always_stop_slow_scripts to about:config since we're
making it also UI-configurable in Pale Moon and it just makes sense not
to hide this option.
This was already in the codebase, but not exposed by default. Mozilla exposed
the pref to fulfill user requests in Firefox 59. Forum users requested the same feaure of pseudo-fullscreen windows. Seems minor enough not to be worth
creating an issue for, since users can already access this by creating a bool
pref.
Ref: BZ 1422535
This removes some hackery surrounding preventing content clicks, and in
general handles auxclick as it should, firing that event on secondary
buttons (wheel/right on default setup for right-handed mouse).
The original state was inverted due to confusion due to a double
negative (not:no_error).
This validation should only be enabled on Windows (for now).
